To all whom t may concern.'

Beit known that I, LEOPOLD B. CosHLAND, a citizen of the United States, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Forming Ice-Packages, of which the following is a speciiication, reference beinef ymade to the accompanying drawings, Forming a part thereof.

My invention relates lto improved devices for freezing water into ice formed in packages of predetermined size-and shape, and the objects ci my invention, among other things, are to provide an improved apparatus, whereby'cakes oi artificial ice oi a smaller size than are usually 'formed in artiiicial ice-plants, may be readily produced, which shall be suitably wrapped andinclosed in receptacles of paper or other simi lar heat-insulating material. By thismeans, paper-inclosed cakes of ice in suitable sizes and of predetermined weight 'for 'family use, may be obtained without sawing or cutting with inevitable waste, and such packages will not only keep the ice-cakes `free 'from dirt or other contamination, but also greatly reduce the melting by preventing air troni reaching the outer surfaces of the individual cakes or'blocks. The aim of my invention,- therefore, is to enable clean, wholesome and pure artificial ice to be produced and delivered to consumers as formed and packed in the ice-making plant, of a specied weight, and with a minimum loss due to melting and chipping ed or breaking of the pieces of the separate cakesthemselves.

My improved apparatus also presents other features of novelty and usefulness to accomplish these and other objects, all ci which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings- Figure 1 is a sectional elevation ci my improved apparatus, showing the partition rack and central upright dividing member inthe ice-can; A

Fig. 2 is a sectional view of the dividing member taken on the line 2-2 of Fig.. 1;

Fig. 3 is a sectional view enlarged, taken on the line 3-3 of Fig. 2;

Fig. 10 is a detail side view of the parts shown in Figs. 8 and 9, looking in the direction of the arrow in'Fig. 8.

Similar numerals refer to similar parts throughout the several figures.

Referring to the drawings (Figs. 1 to 5), 11 indicates a vertical container or ice-can of suitable size and shape, such as are usually employed in plants for the manufacture of artificial ice. These cans are usually made of galvanized sheet-metal, slightly tapering toward the bottom, and the can 11 has the cover 12 adapted to iit over the top of the can 11, as shown in Fig. 1. 13 indicates the removable partition rack which is arranged'within the can l1, as shown; the rack 13 comprises 'a series of horizontal Patented .nay a, reir.

plates lll which are suitably affixed or riveted through flanges to the central dividing member 15, which is vertically disposed in the rack 13, and divides same into an equal number of package spaces 16 arranged in tiers on either side of the member 15, as shown in Fig. 1. The supports 17 hold the separate plates 14 in position at their corners.

The member 15 comprises two oppositely disposed plates 18 and 19, 'which lie in substantial parallelism and are sealed by plates on their ends and sides, as shown in Fig. 2, thereby forming a hollow member; within the hollow space so formed, are secured, in any suitable manner, the upright dividing plates 2O and 21, forming, within the member 15, three separate chambers 22, 23, and 2li, eX- tending vertically through the member 15, the chambers 22 and 24 constituting air chambers on either side of the central water flue chamber 23. The top of the water flue 23 has an opening 25 formed therein through which the blower-pipe 26 projects downwardly, as

shown in Fig. 1. The pipe 26 is connected with a suitable source of supply 4of compressed air (not shown). A water overflowpipe 27 is secured to the top of the water flue 23 to carry ofi`| any excess supply of water'in the flue '23 when the freezing operation is being carried out. 28 indicates a series of passages formed'in the plates 18 and 19, oppositely disposed in pairs, and preferably located near the top of the separate spaces 16, as shown in Fig. 3. These passages 28 are preferably. rectangular in shape, as shown in Fig. 2, though I do not wish to limit myself to the form or location of such passages leading into the flue 23 from the different spaces 16.

29 represents the ice-package proper, consisting of a vrectangular carton or container,

shown in Fig. 5, preferably made of parf afiined paper which serves not only to shed the water from the ice as it melts, but also to reduce such melting to a minimum by preventing air from reaching the outer surfaces of the ice-cake inclosed within. As shown in Fig. 5, the container 29 has a rectangular slot 30 cut' in one of the sides, preferably of the same size as the passages 28,

and adapted to aline' therewith, as shown in Fig. 3. lIn the side of the container 29,`

opposite' to the slot 30, is formed the hole 31 which allows water to enter the successive containers in the different tiers in the rack 13 as the can 11 is filled with water preparatory to freezing.7 The slots 30 act as air and surplus water vents emptying into the water flue 23, as shown in Fig. 3.

Referring to the modification shown in Figs. 6 and 7 the plates 14 have holes 32 cut therein, as shown in Fig. 6, through which theblower-pipes 33 and v34 project and extend nearly to the bottom of the can l11. The holes 32 act as air and water passages, and are used in lieu of the passages 28 and slots 30 in the preferred construction shown in Figs. 1 to 5. The dividing member 15 in this modified form consists of the plates 18 and 19 sealed at their sides and ends, forming the hollow member having the interior dividing plates 2O and 21 to create the two air chambers 22 and 24, and the water due 23' as in the preferred embodiment, but without having the passages 28 cut inthe plates 18 and 19. rIhe container 29', shown in Fig. 7, has the vertically disposed holes 35 and 36 cut in the top and bottomlof the container respectively, and .these holes 35 and 36 are arranged to aline vertically'with the diierent holes 32 cut in the plates 14, as shown in Fig. 6. When water is poured into the can 11, the successive containers 29 are lled by having the water rise and enter through the lower holes 36, while the air escapes from the successive containers through upper holes 35 as the level of the water rises through the quired. I have shown one `means of vertically adjusting these plates 14 on the central dividing member 15 in Figs. 8,; 9 and 10. The plates 14 are mounted on flanges 37 which carry the yscrew-.threaded bolts 38 and 39, which in turn support the inner plates 40 adapted to seal in all positions the openings 41 cut in the side plates 18 and 19. The flanges 37 have formed therein the rectangular slots 42 which correspond in` size and shape to the slots 30 shown in Fig. 2, and perform the same functions. 8, the space 16 is restricted for an ice-cake of small size; in Fig. 9, the plates 14 and langes'37 have been separated from one another, as shown by the arrows, thereby enlarging the container-space 16, while access to the water flue 23 continues to be preserved by the slots 42 always affording'a free and unobstructed passage from the containers 29 to the water flue 23, as in the preferred embodiment.

The method of utilizing this apparatus in the manufacture of the ice-packages is substantially as follows: The containers 29, made of suitable size and shape, are placed in package spaces 16 so that they t snugly therein, as shown in Fig. 3. Then the rack 13, loaded with its full quota of containers, is placed in the ice-can 11 in which the water will be poured, which willill each of the containers 29 in the diderent tiers successively, and also the water flue 23 through the slots 39 and passages 28. The ice-can 11 with its cover 12 is then immersed in the brine or `,other freezing mixture, and the water in the containers is gradually 'transformed 4into ice, the freezing working toward the'central dividing member 15, by reason of the fact that the water adjacent the walls of the can 11 freezes first. As soon as the can 11 has been immersed, the blowpipe 26 is inserted inthe-water flue 23, and compressed air is forced to the bottom of the Hue which keeps the water agitated and bubbling in this ue, tending to draw any impurities in the water within the sevyeral conlected at the top of the flue 23, due to the air In Fig.

blast, and passes out of the Water flue 23 through the pipe 27.

In the modified form shown in Figs. 6 and 7 the pipes 33 and 34 perform the same function as the pipe 26 in keeping the water agitated by the air blast, the pipes being withdrawn before the ice-packages have been completely frozen.

When the freezing has been completed, the rack 18 is lifted out of the can 11, and on heating the plates 14 and other metallic parts of the apparatus by any of the customary methods, the ice-packages may be readily removed from their individual spaces in the rack, the paraffined paper aiding this operation, and are then ready for delivery to the consumer.

Many variations in form and dimensions may be made in my apparatus without departing from the principles of my invention, and without sacrificing any of its advantages.
